Soil liquefaction is a phenomenon where soil that is saturated with water suddenly loses its strength and behaves like a liquid. This usually occurs due to sudden, large stresses on the soil — for example, from an earthquake. This can be very dangerous for buildings sitting on top of the soil, as they can suddenly sink into the ground! The embedded video explains soil liquefaction in more detail.
Is there a way to prevent soil liquefaction? Do you think adding certain materials to…

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum…

What is geomagnetism, and how does it affect the earth? Visit the USGS Geomagnetism program for more information about this invisible force (USGS, 2006). How is the earth's magnetic field patterned? Are the magnetic poles located at the exact North and South Pole? How can the fields be mapped on the Earth's surface? What is declination? Use the mapping tools to study changes in declination patterns over time. (USGS, 2006)

Are you fascinated by dinosaurs, fossilized bones, and fossilized plants? Although this project is not based on actual fossils, you will get good practice at reconstructing an animal's skeleton from individual bones. You'll use what you find to identify the types of prey that owls consume.

What causes landslides? The USGS Landslide Hazards Program conducts research needed to answer major questions related to landslide hazards. Where and when will landslides occur? How big will the landslides be? How fast and how far will they move? What areas will the landslides affect or damage? How frequently do landslides occur in a given locality? Investigate the patterns of landslide occurrence in your area. Are they related to locations, geology, or topography? Are they more frequent…

Have you ever noticed an old stone wall and wondered how long it has been there? If there is lichen growing on the wall, the lichen has most likely been living there since the time the wall was made, so if you could figure out how old the lichen is then you could deduce the age of the wall. Geologies use this method, called lichenometry, and other methods to establish dates and temporal sequences as they seek to construct a history from the available evidence. In this geology science project,…

Minerals are sometimes precious, like diamonds. But most minerals are very common, like sodium, which is found in salt. How are minerals found and identified? How are our mineral resources distributed? Visit the USGS Mineral Resource Program to find mineral resources in your state. How are satellite images used to identify potential mineral sources? You can also find out how minerals are identified using spectroscopy. How are potentially harmful minerals, like mercury, dealt with? Visit the…

Soils are made of particles of different types and sizes. The space between particles is called pore space. Pore space determines the amount of water that a given volume of soil can hold. Porosity is the percentage of the total volume of soil that consists of pore space. Compare the porosity of different types of soil. Which types of soil hold the most water? Can you see this under a microscope?

Have you ever heard the expression, "solid as a rock"? As it turns out, rocks are not entirely solid. Rocks actually have tiny pockets of air inside them. This is obvious when you look at a piece of volcanic rock (often called basalt), which is full of visible holes. But dense rocks, such as granite, have tiny air pockets inside them, too. These pockets of air are just much smaller.
If you picked up one volcanic rock as well as one granite rock of the same size, you would notice they don't…

Is soil structure an important factor in earthquake dynamics? Investigate soil liquefaction and how different soil types respond to earthquake movements. Are movements more dramatic in sandy/loamy or clay type soils? Which soil structures are most stable? Which are the most volatile? (MCEER, 2005)
